How to Reset Engine Light on Smart Car

Safety First

Before you begin, it is important to take some safety precautions. Make sure your car is parked on a level surface and that the engine is turned off. Disconnect the negative battery terminal to prevent any electrical shocks.

Method 1: Using a Code Reader

The easiest way to reset the engine light on a Smart car is to use a code reader. This is a small handheld device that can read and clear diagnostic trouble codes (DTCs) from your car’s computer.

1. Connect the code reader to the OBD-II port under the dashboard.
2. Turn on the ignition, but do not start the engine.
3. Follow the instructions on the code reader to read and clear the DTCs.
4. Once the DTCs have been cleared, start the engine and check if the engine light is still on.

Method 2: Using the Pedal Dance

If you do not have a code reader, you can reset the engine light on a Smart car using the “pedal dance.” This method involves pressing a sequence of pedals on your car’s dashboard.

1. Turn on the ignition, but do not start the engine.
2. Press the accelerator pedal three times within five seconds.
3. Press the brake pedal three times within five seconds.
4. Repeat steps 2 and 3 two more times.
5. Start the engine and check if the engine light is still on.

Method 3: Disconnecting the Battery

As a last resort, you can reset the engine light on a Smart car by disconnecting the battery. This will erase all of the data stored in the car’s computer, including the DTCs.

1. Disconnect the negative battery terminal.
2. Wait at least 10 minutes.
3. Reconnect the negative battery terminal.
4. Start the engine and check if the engine light is still on.

Warning

If you have tried all of the methods above and the engine light is still on, it is important to take your car to a mechanic. This could be a sign of a more serious problem that needs to be addressed.
